Not sure if this is a bug in pov or the docs (or possibly my brain).
The docs (6.1.5.5) say:
"For example...
color My_Color red 0.5
this substitutes whatever was the red component of My_Color with a red component
of 0.5 however...
color My_Color + red 0.5
adds 0.5 to the red component of My_Color"
But the following scene-file seems to contradict this:
#version 3.5;
#declare ColTest1 = rgb<1,1,0>;
#declare ColTest2 = rgb<0,1,1>;
//legal
#declare Foo = ColTest1 + ColTest2;
//not legal
#declare Foo = ColTest1 ColTest2;
#declare Foo = ColTest1 + blue 1;
#declare Foo = ColTest1 blue 1;
Any comment as to whether I should post to bugs, docs, or what?
